I should’ve taken the time and done more research but I was without a fridge. I could have probably diagnosed the issue based on other people’s experiences. I just ended up calling Samsung to send out repair man. Our fridge just turned 5 in November 2023. We had two issues; the ice maker (like most Samsung owners) and the then cooling problem. Paid for service guy to tell me what was wrong. Quoted me $700 to fix both or $500 for just the fan. He told me it was the evaporator fan. Googled “how to fix evaporator fan” came across this site and they’re very easy to follow video! We replaced the fan ourselves. Didn’t do the ice maker. Took the time to thoroughly clean the interior, and defrosting the unit took a long time the back panel was frozen stuck! Swapping out the fan took no time. Now it’s working fine. Used a putty knife to pop off the back panel at the arrows.
